Imperial 425-CB Replacement Gauge

The Imperial 425-CB Replacement Gauge is a professional-grade low side manifold gauge designed for precision pressure monitoring in HVACR systems. As a veteran-preferred 2-1/2 inch replacement gauge, this unit features a blue color-coded faceplate for immediate identification on the manifold’s low-pressure side. Engineered with a 1/8" NPT male connection, it provides a secure, leak-free fit for standard manifold sets. This compound manifold gauge is calibrated for high-accuracy readings across a 30 inHg to 350 psi range, making it compatible with legacy and modern refrigerants including R-12, R-22, and R-502. The resilient internal movement is designed to mitigate the effects of vibration and shock, ensuring a steady needle and flutter-free performance during critical diagnostic and charging procedures.

• Durable Construction: Features a robust design that withstands rigorous field conditions and helps extend service life.
• Enhanced Accuracy: Built to ANSI standards with a +/-3-2-3% accuracy rating for reliable system diagnostics.
• Vibration Dampening: Internal mechanisms are isolated to reduce rapid needle movement, ensuring easy readability on HVAC manifold sets.
• Universal Compatibility: Fits most standard Imperial and aftermarket manifolds requiring a 1/8" MPT back mount connection.

• What refrigerants are listed on the dial? The faceplate is specifically calibrated for R-12, R-22, and R-502 scales.
• What is the maximum pressure rating? This low side gauge monitors vacuum up to 30 inHg and positive pressure up to 350 psi.
• Is the boot included? This specific model is for the replacement gauge only; however, it fits standard color-coded protective boots.
